Specialization of member template of non-specialized class template

[razvyb...@gmail.com]

Paragraph 18 of [temp.expl.spec] states that:

A specialization of a member function template, member class template, or static data member template of a non-specialized class template is itself a template.

But the paragraph right above (paragraph 17 of [temp.expl.spec]) explicitly states that you cannot explicitly specialize a class member template if the enclosing template is not specialized.

Then what kind of specialization does paragraph 18 actually refer to?

Thank you.
